Patent number: 9610929Abstract: An air braking unit for use in an air braking system. The air braking unit is arranged to be positioned, in use, at a vehicle wheel, and comprises an inlet for receiving, in use, compressed air from a central source. At least one first valve is arranged to selectively allow compressed air from the inlet to enter a wheel brake chamber in use. At least one second valve is arranged to selectively allow air from the brake chamber to be released via an outlet to the atmosphere in use and control means controls the first and second valves to operate to selectively control the air pressure in the brake chamber in use.Type: GrantFiled: August 9, 2007Date of Patent: April 4, 2017Assignees: Haldex Brake Products Ltd., Camcon Technology Ltd., Cambridge Enterprise LimitedInventors: Wladyslaw Wygnanski, David Cebon, Frank Kienhofer, Robert Prescott

Patent number: 9404602Abstract: An electromagnetic valve comprises a yoke, a magnet having pole pieces defining a gap, a flexure assembly having one end attached to the yoke such that part of the flexure assembly extends into the gap, and a mechanism configured to polarize the magnetizable portion so that the extending part of the flexure assembly is attracted towards a pole piece by a magnetic force, thereby defining a valve state. The flexure assembly has at least one resilient portion and at least one magnetizable portion, wherein the extending part of the flexure assembly is movable between the pole pieces through an intermediate position towards which it is resiliently biased such that a resilient mechanical force is generated by deflecting the resilient portion from an undeflected position. The magnetizable portion and the resilient portion are configured such that the magnetic force defining the valve state is greater than the resilient mechanical force.Type: GrantFiled: March 11, 2014Date of Patent: August 2, 2016Assignees: Cambridge Enterprise Limited, Camcon Technology Ltd., Haldex Brake Products Ltd.Inventors: David Cebon, Andrews Odhams, Neil Houghton, Wladyslaw Wygnanski, Jonathan Miller, Robert D.

Publication number: 20060037257Abstract: A method for controlling the collapse of a building having multiple floors. The method comprises the step of providing at least one load-bearing strut between at least one set of adjacent floors and attached to the load-bearing structure of the building, the strut being constructed such that, under building collapse conditions, it absorbs enough of the energy released during collapse of the building to control the rate of collapse of the building to reduce damage thereto. A building collapse control system is also provided.Type: ApplicationFiled: May 27, 2003Publication date: February 23, 2006Inventors: David Newland, David Cebon

Patent number: 4984128Abstract: A load sensor which has an elongate hollow body 11, preferably formed as a metal extrusion, and which forms a first capacitative plate 21. A second parallel capacitative plate 15 is formed on an insulating body which is held in place relative to the extrusion by a resilient support 16. Application of a load to the extrusion causes variation in the gap between the plates of the capacitor, thus affecting the capacitance in a manner which is measured and processed to provide an output signal which is directly proportional to the applied load.Type: GrantFiled: March 30, 1989Date of Patent: January 8, 1991Inventors: David Cebon, David J. Cole, Michael S. A. Hardy, David E. Newland
